copartnership Application November 1, 1935, Serial No. 47,893

3 Claims.

This invention relates to hand tools and particularly to hand tools forperforming riveting, punching operations and the like.

It is an object of the invention to provide a tool of the classreferred. to the parts of which can be so cheaply made and so cheaplyassembled that the tool can be sold to the consumer at so low a price asto make it available to the individual user who has heretofore beenunable to afford the price of a tool of this class.

Another object is to provide tool of this class which can be easily andcheaply made and assembled but which will be simple and durable inoperation.

Another object is to provide, in a tool of the class referred to,improved means for yieldably supporting a movable riveting element.

Another object is to provide generally an improved tool of the classreferred to.

Other objects will be apparent to those skilled in the art to which myinvention appertains.

My invention is fully disclosed in the following description taken inconnection with the accompanying drawing, in which:

Fig. 1 is a side elevational view with parts broken away of a preferredembodiment of my invention;

Fig. 2 is a sectional view taken from the plane 2-2 of Fig. 1;

Fig. 3 is a fragmentary elevational view taken from the direction of thearrow 3 of Fig. 1;

Figs. 4 and 5 are, respectively, side elevational and end views of atool element which I may employ instead of that illustrated in Fig. 1;

Fig. 6 is a View illustrating the tool of Fig. 1, performing anoperation with the tool element of Figs. 4 and 5;

Fig. 7 is a fragmentary sectional view taken from the plane I of Fig. 1.

Referring to the drawing, I have shown generally at I a main framecomprising a base 2 having on the lower side thereof a tongue 3' andshoulders 44. The tongue 3 is adapted to be inserted between the jaws ofa vise shown at 45 5 in broken lines, Fig. 3, and clamped th-erebetweento support the device, the shoulders 4-4 resting upon the jaws toposition the device.

A yoke 6, preferably T-form in section, having a rearwardly extendingrib I, rises from the base 50 2 and has a bearing 8 thereon above theforward end of the base 2. The base 2, yoke 6 and bearing 8 arepreferably all formed integrally as for example in a casting. Extendingentirely through the base is a bore 9 and aligned there- 55 with is abore ID in the bearing 8.

In the bore 9 is preferably inserted the shank ll of a lower rivetingtool |2 having a collar l3 resting on the base when the shank II is inthe bore 9, and provided as at l4 with an elevated portion upon which ariveting operation may be performed.

In the bore I is reciprocably mounted a cylindrical riveting tool I5which may have a conical point IS on the lower end to facilitate theriveting operation and at its upper end I! may project upwardly beyondthe bearing 8. Means to be described is provided to'support the tool |5in the bearing but permit it to be driven downwardly when struck a blowwith a hammer upon the upper end Ill; and as will now be apparent, bysuch action, a riveting operation may be performed, for example on arivet |8 resting upon the lower riveting element l2 and in a piece ofwork IQ, for any purpose. As illustrative of such uses is the rivetingof rivets in the operation of relining brakes for vehicles.

The bearing 8 has a pair of openings 20 20 at opposite sides thereofopening into the bore I0, opposite sides of the; tool I5 beingexteriorly exposed in the opening 20.

A hairpinform or U-form spring 2|, preferably made from wire, isprovided straddling the rib I of the frame and at its free ends as shownat 2222, Figs. 2 and 7, resiliently gripping or pinching therebetweenopposite sides of the tool I'i. The tool is thus supported in the boreID. If the tool tends by gravity to slide downwardly in the bore theends 22-22 of the spring will be prevented from sliding by engagementthereof with the sides of the openings 2020 and the frictionalengagement between the ends of the spring and the tool will prevent itfrom sliding and will support it.

Onthe other hand, however, the tool I5 may be grasped between the thumband finger of the operators hand and it will yieldably slide in the boreto position it above the work l9; and in any position to which it isreeiproeably moved, it will remain by the friction provided for as abovedescribed.

To support the rear end of the spring 2| and to position the free ends2222 thereof, the closed end portion 23 of the spring may be lodged in anotch 24 in the relatively thin outer edge of the rib I.

The device thus far described will be seen to be relatively simple,consisting only of the frame I and the two tools or tool elements l2 andI5, and the spring 2|; but to insure that the production cost of thedevice will be as small as possible, provision is made to facilitateassembly of the parts particularly the spring 2| with the frame. To thisend, the openings 20 have a groove or grooves 25 formed in the side ofthe head 8 and leading into the apertures, and the spring 2| is formedof sufiiciently heavy wire so that when spread apart to engage theopposite sides of the tool shank [1, it will exertthe necessarysuspending friction and at the same time before it is assembled inworking position and the ends of the wire are at their greatestproximity to each other, they will still be spaced apart sufliciently toeasily be straddled over the edge of the rib 1. With the'spring thusconstructed, the ends thereof may be conveniently straddled over the rib1 at a point such as that at 26 in which the spring is diagonallydisposed so that the greater part thereof may extend beyond the rib land be engageable by the hand of the assembler. The ends of the springare then slid into the'grooves which lead them into the openings 20;then the outer end of the spring is rocked around to the notch 24 andthrust into it. The successive movements of the closed end of the springto assemble it are indicated by the arrows 21 and 26, a final movementnot indicated being required to finally. lodge the closed end in thenotch 24.

By this process of assembling, a much stronger spring can be employedthan otherwise because a stiff spring will cause delay in the operationof assembling it'with the rest of the tool, in the absence of means toguide it to its position.

Upon removing, the lower riveting element l2, the tool may be used topunch holes or to knock out rivets, the latter operation beingillustrated circular section punch or the like and that the same may beoperated by a hammer blow on the end thereof as described for the toolHi.

My invention is not limited to the exact details of constructionillustrated and described. Changes and modifications may be made withinthe spirit of my invention without sacrificing its advantages and withinthe scope of theappended claims.

I claim: 7

1. In a tool of the class described, a C-form frame comprising anoutwardly extending rib having an outer edge portion, and a bearinghaving a cylindrical bore therein, the bearing having opposite openingsprovided in the wall of the bore, the bore receiving a cylindrical toolshank reciprocably therein, a notch in the outer edge portion of therib, a U-shaped spring having the closed end engaged in the notch andhaving its legs frictionally gripping therebetween through the openingsopposite sides of a tool shank in the bore.

2. In a tool of the class described, a C-for'm frame comprising anoutwardly extending rib having an outer edge portion, and a. bearinghaving a bore therein, the bearing having opposite openings provided inthe wall of the bore, the bore receiving a tool shank reciprocablytherein, a notch in the outer edge portion of the rib, a U- shapedspring having the closed end engaged in the notch and having its legsfrictionally gripping therebetween through the openings opposite sidesof a tool shank in the bore.

3. In a tool of the class described, a C-form frame, a head having abore therein, the head having an opening in the wall of the bore, thebore receiving a tool shank reciprocably therein, a notch in the outerconvex portion of the C-form frame, a U-shaped spring having the closedend engaged in the notch and having its legs disposed on opposite sidesof the head and having a portion of a leg in said opening frictionallyengaging, through the opening, a side of a tool shank in the bore.
